Addressing Pseudoreplication in Experimental Studies

We believe that good investigators who are aware of the issue will find that eliminating pseudoreplication from their experiments is a relatively straightforward matter. The problems of pseudoreplication that we typically encounter in published studies are easily solvable, and we see no reason that reviewers and editors should accept studies that fail to eliminate pseudoreplication. We certainly do not believe that absence of pseudoreplication should be the sole, or even the main, criterion for evaluating experiments. Rather, we see the absence of pseudoreplication as representing a minimum requirement that should be met before the merits of an experiment are evaluated.
